INSUL'ATED RAIL JOINT.

Original applicationy filed September V6, 1921, Serial No. 498,609.Divided'and this application led November 30, 1921.

To all whom t may concern Be it known that I, ALFRED L. RUTHVEN, acitizen of the United States, residingl at Rochester, in the county 0fMonroe and State of New York, have invented certain new and usefulImprovements in Insulated Rail Joints, of which thefollowing is aspecification, reference being had therein to the accompanying drawing.

The present invention relates to insulated rail joints for useinrailw'ay signalling or train controlling apparatus, and this appli'-cationis azdivision of thefcopending application for patent on simplextrain control filed September 6, 1921, Serial.No.-498,609.

The object off'the'invention is to provide a novel and improvedinsulated joint lfor the trailc rails, in order to obtain insulationwhich will'n'otbreak down, as well as efficiently supporting the railends and preventing the rail sections from creeping.

With the foregoing and other objects in view, which will be apparent asthe description proceeds, the invention resides in the construction andarrangement of parts, as hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimed,without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, whereinvFigure 1 is a Side elevation showing the improved insulated rail joint.

Fig. 2 is an enlarged section on the line 2 2 of Fig. 1.

Fig. 3 is a side elevation of a modied form of insulated rail joint.

One form of insulated rail joint is shown in Figs. 1 and 2, wherein theinsulating plates or sheets 90 are disposed between the adjacent ends ofthe rail sections 91, and fish plates or bars 92 of wood or otherinsulating material are secured to the opposite sides of the rail websby means of the usual bolts 93. Said sh bars are suliciently stout toassist in holding the rail sections together in alinement. Two pairs ofside plates 94 are secured by the bolts to the bars 92, and the adjacentends of said plates are spaced apart so as to be insulated from oneanother, with only the bars 93 extending from one rail section to theother across the insulation between the rail sectionsE The into the tie.

secured to the tie, which will fasten` the rail serial Na'sisro.

plates-94 havelower inturned flanges 975 to extend under the baseflanges of the rail `sec-tions, and the flanges 95 of the two pairs ofclamping plates have `depending abutments 96 disposed at opposite sidesof the tie V97 which is disposed under the joint.

lAngle plates 98 arey preferably tted` on the tie 4over the uppercorners tliereofso that the flanges 95 and :abutments bear against saidplates, as seen in Fig..1. The abutments 96 of veach pair are securedtogether by transverse bolts 99 extending through them, and theabutments are secured to the tie 97 at the opposite sides by meansofilag screws 10.0 extendinglthrough the abutments and The'abutments arethus firmly sections down von the tie, and also prevent the creeping'ofthe rail joint on the tie. The tie 97 is supported 0n a concretesleeper or base 102 embedded in the roadbed, said sleeper or base havingan upper groove or channel 101 receiving the tie, to retain the tie inplace. Bars or shims 103 of wood Ior other suitable material aredisposed in thechannel 101 under the tie 97, for cuslin ioning the tieand also supporting it at the desired height in either horizontal orinclined position according to the track. A plate 104 of insulatingmaterial is disposed under the ends of the rail sections on the tie 97between the flanges 95, and is held in place by lugs 105 extending fromthe adjacent ends of said flanges and overlapping the ends of said plate104.y With this construction, there is no metal extending from one railsection to the other, and the parts 90, 92, 97 and 104 between the railsections are all of insulating material, s0 that the insulation will notbreak down. The joint is also firmly supported and is prevented fromcreeping.

l disposed Abutments 96 are clamped to the rail sections and abut theopposite sides of the sleeper 102, to prevent the rail from creeping.

Having thus described the invention, What is claimed as new is zl. Aninsulated rail joint comprising spaced clamps for the end portions ofthe rail'sections having portions to extendunder the base flanges of therails and abutm'ents below said portions to abut the opposite sides of asupport on Which-said portions are 2. An insulated rail joint comprisingspaced clamps Afor the end portions of the rail sections, each clamphaving opposite side members With portions to extendunder the 'baseanges of the corresponding rail section, said portions having dependingabutments` to abut a support on which said -portions are disposed.

3. An insulated rail joint comprising 'spaced clamps for the endportions of the rail sections, each clamp having opposite side memberswith portions to extend under the base flange of ythe corresponding railsection, said portions having depending abutments to abut alsupport onwhich said portions are disposed, said abutments of each 4clamp beingsecured together.
